MULTIPATH SLIT AEROPHOTOGRAPHIC APPARATUS Russian patent published in 1995 - IPC

FIELD: aerophotography. SUBSTANCE: aerophotographic apparatus has objective 1, two at least exposure slots 4, surfaces 2 for receiving images (the surfaces are mounted behind the slots) and unit for shifting surface of image reception. Objective 1 is ball objective and has spherical focal surface. Surface 2 for receiving image is disposed at equalizing table 3 in form of elliptical cylinder. Large half axis of the base of the cylinder is parallel to one optical axis of ball objective 1 and is equal to its focal length. Generating line of elliptic cylinder is oriented relatively the direction of image motion. Longitudinal line if medium part of the slot 4 has to be the arc of the circle which is disposed at spherical focal surface of objective 1. EFFECT: improved precision. 2 cl, 6 dwg, 1 tbl
